Help Plant Trees on Earth Day

Posted on: April 10th, 2018 by Leslie_Zucker

Trout Unlim­ited is look­ing for vol­un­teers to help plant trees for Earth Day.

In col­lab­o­ra­tion with the Ashokan Water­shed Stream Man­age­ment Pro­gram (AWSMP) the Catskill Moun­tains Chap­ter of Trout Unlim­ited is orga­niz­ing a tree plant­ing project on Bush Kill, along Wat­son Hol­low Road in West Shokan on Sat­ur­day, April 21, the day before Earth Day, from 9:30–2:00.

When: Sat­ur­day April 21st

Time: 9:30AM – 2PM

Where: Ashokan Water­shed Stream Man­age­ment Pro­gram office, 3130 Route 28, Shokan, NY 12481. (If you arrive after 10, please head straight to the plant­ing site at 269 Wat­son Hol­low Road, West Shokan, NY. There is lim­ited park­ing at the site, though, so please try to arrive at the meet­ing site between 9:30 and 10:00.)

Con­tact #: 845–802-3861 (Andrew Higgins)

Please Reg­is­ter Online:

Meet at the AWSMP at 9:30 for sign in. We’ll car-pool to the site, where there’s lim­ited parking.

CMTU and vol­un­teers will be plant­ing native trees and shrubs along Bush Kill in part­ner­ship with the Arbor Day Foun­da­tion. The goal of this project is to plant along crit­i­cal cold­wa­ter streams in the Catskill Moun­tain Region. The plant­ing will help sta­bi­lize the stream­bank along the creek to reduce ero­sion and pro­vide shade to keep the water cold and clean!

We are look­ing for at least a dozen vol­un­teers to help. You are not required to be a TU member.

Jobs include: coor­di­nat­ing vol­un­teers, plant­ing trees, water­ing, reg­is­tra­tion table. Please con­sider tak­ing one day out of the year to help ful­fill the mis­sion of Trout Unlimited.

Please join us and bring a friend.

Taking Flight 2018 Warbler Weekend

Posted on: April 4th, 2018 by Leslie_Zucker

Did you know the Catskill Moun­tains host 27 dif­fer­ent breed­ing war­blers and at least 9 more species that have been doc­u­mented pass­ing through the region? The Catskill Cen­ter is host­ing Tak­ing Flight 2018 War­bler Week­end from May 25–27 at the Emer­son Resort & Spa in Mt. Trem­per. Check out the con­fer­ence high­lights and sched­ule for oppor­tu­ni­ties to learn how native Catskill plants in bird-friendly back yards sup­port our native birds. If your yard con­tains a stream in the Ashokan water­shed, con­tact Bobby Tay­lor, Catskill Streams Buffer Coor­di­na­tor at (845) 688‑3047, ext. 6 or to learn how native plant­i­ngs can pro­tect prop­erty and habitat.


Spring Migration Underway

Posted on: March 30th, 2018 by Leslie_Zucker

Every spring, dozens of species of land­birds migrate from win­ter­ing grounds as far away as South Amer­ica to their sum­mer breed­ing grounds in the United States and Canada. The migra­tion period is one of the most per­ilous stages in the life cycle for birds, and the wide­spread loss of stopover habi­tat where they can rest and replen­ish their energy is believed to be a con­tribut­ing fac­tor in the decline in pop­u­la­tions for a num­ber of migra­tory bird species.

A new study has iden­ti­fied the Catskills region as one of the most impor­tant stopover loca­tions in the North­east! And stream cor­ri­dors are impor­tant habi­tat for birds that seek access to food, rest and water. One thing any landowner can do to help is use native plants in land­scap­ing. Native plants result in well fed birds! To learn more about which Catskill native plants improve wildlife habi­tat in stream cor­ri­dors, visit the Catskill Streams Buffer Ini­tia­tive (CSBI) web­site. Water­shed landown­ers can also con­tact CSBI Coor­di­na­tor Bobby Tay­lor for free assis­tance with restor­ing stream­side habi­tats at or (845) 688‑3047 ext. 6.

With sup­port from the U.S. Fish and Wildlife Ser­vice and other part­ners, researchers from the Uni­ver­sity of Delaware used inno­v­a­tive analy­ses of weather data cou­pled with field sur­veys to pre­dict poten­tially impor­tant stopover sites for migra­tory land­birds in the North­east region. The final report and maps are avail­able in the North­east Stopover Sites for Migra­tory Land­birds gallery on Data Basin.


Leprechaun Bees in Search of Native Plant Gold!

Posted on: March 23rd, 2018 by Samantha Kahl

It’s spring now and because St. Patrick’s Day just passed, we are tak­ing a look at one of nature’s small­est lep­rechauns.… Augochlorop­sis metal­lica, a type of Sweat Bee. Native and metal­lic green, metal­lica is smaller than a Honey Bee!

Augochloropsis metallica (head)

Since these bees are so small, it takes a keen eye to spot them. Augo­chorop­sis metal­lica is found through­out the United States, from Ontario to Florida, and as far west as Ari­zona! They are usu­ally around from March until Novem­ber, with their flu­o­res­cent emer­ald green bod­ies shim­mer­ing in the daylight.

These beau­ti­fully tiny native bees have been sighted in two loca­tions around the Ashokan Water­shed, Stony Clove Creek in Greene County, and in Oliv­erea of Ulster County! What makes this bee so spe­cial is that it plays a cru­cial role in pol­li­nat­ing our native plants, pro­vid­ing a fight­ing chance for our native plant species to stand up against inva­sive plant species.

If you want to try and see the emer­ald metal­lica bee, make sure to plant native plants in and around your yard!

To pur­chase your plants locally, the Ulster County Soil and Water Con­ser­va­tion Dis­trict will be hold­ing their annual Bare Root Seedling Sale in April! Orders must be placed by Fri­day, March 30th using this order form, with pick-up dates being held on Wednes­day April 18th at Ulster County Fair­grounds in New Paltz and Fri­day April 20th at Ulster County Depart­ment of Pub­lic Works in Kingston. If you miss the dead­line, left-over sin­gle stem stock is usu­ally avail­able for walk-up pur­chase at the two loca­tions listed above.

Happy plant­ing, and thank you for sup­port­ing the bees!

The recent Nor’easter shows just how dev­as­tat­ing and dis­rup­tive high winds cou­pled with snow and ice can be. Even today, three days after the storm, thou­sands, includ­ing many in the water­shed are still with­out power. Presently, another Nor’easter is fore­cast to hit the region this Wednes­day. There are actions you can take today to be pre­pared and lessen the impact win­ter storms have on you and your family.

A great resource is the NY Exten­sion Dis­as­ter Edu­ca­tion Net­work (NY EDEN) page that deals with Win­ter Storms. As with many other types of dis­as­ters it is impor­tant to have a emer­gency bag or kit with sup­plies in your home. Items that could be included in the kit include:

  • One gal­lon of drink­ing water per per­son per day (for the assumed length of time you will be with­out water)
  • Non-perishable food items (such as canned food) and can opener
  • First Aid Kit
  • Flash­light
  • Bat­tery pow­ered AM/FM radio with batteries

Here are more ways to pre­pare and stay safe:

Be sure to have suf­fi­cient fuel since it may not be pos­si­ble for deliv­er­ies to be made for sev­eral days. Try to fill vehi­cle fuel tanks prior to the storm and keep sev­eral con­tain­ers of fuel ready for refu­el­ing. If you do lose power, do not run a gen­er­a­tor or propane grill inside your house as you may be poi­soned by car­bon monox­ide fumes. Dress in lay­ers to stay warm and use extra blan­kets in bed. If you use a fire­place or wood stove, be sure to have fire extin­guish­ers ready and that smoke detec­tors and car­bon monox­ide detec­tors have fresh batteries.

Espe­cially this time of year, snow tends to melt quickly and could con­tribute to flood­ing. Do not drive over flooded road­ways as the depth of water is often deceiv­ing and deeper than it appears. Turn Around! Don’t Drown!

Do not attempt to drive over or move downed power lines as it is often dif­fi­cult to deter­mine if they are live or not. Downed lines in stand­ing water can poten­tially be an elec­tro­cu­tion haz­ard so stay clear of them. Report the downed lines to your elec­tric com­pany. Unless you are expe­ri­enced with the use of a chain­saw, do not try to cut up downed trees on your own. This is espe­cially true if the trees are tan­gled up in downed power lines. Leave their removal to professionals.

Use the time we have now to pre­pare for the next storm so you will have the least amount of disruption.

National Invasive Species Awareness Week — Water Chestnut

Posted on: March 2nd, 2018 by Samantha Kahl

Wel­come to the final day of National Inva­sive Species Week! Thank you all for stick­ing with us. We hope you’ve learned a great deal and will con­tinue efforts in pre­serv­ing our native species! Last, but not least, we look at the aquatic inva­sive Water Chestnut.

Water Chest­nut is native to Eura­sia and Africa, intro­duced to the U.S. in the mid-1800’s as an orna­men­tal plant. It is found in fresh­wa­ter lakes and slow-moving streams and rivers. First notice in Sco­tia, NY, Water Chest­nut occurs in 43 coun­ties across New York State.


Water Chest­nut is an annual plant with float­ing triangluarly-shaped leaves con­tain­ing saw-toothed edges. The sub­merged, hol­low air-filled stems grow 12 to 15 feet in length that anchor them­selves in the soil. Four-petaled, white flow­ers bloom in June, with fruits con­tain­ing 4-inch spines with barbs. Seeds within the fruits remain viable up to 12 years. The fruits are key in spread­ing Water Chest­nut, as they detach from the stem and float to another area. The barbs aid in attach­ing the fruit to recre­ational water­crafts and fish­ing equipment.

So what’s the prob­lem?

Water Chest­nuts con­tain dense root mats that make water recre­ation extremely dif­fi­cult to get through. These dense mats also shade out native plants, which pro­vide food and shel­ter to native  fish, birds, and insects. When the dense mats decom­pose, the chem­i­cal processes involved decrease the amount of dis­solved oxy­gen in the water, poten­tially suf­fo­cat­ing fish and plant species. The fruits of the Water Chest­nut are often found along the shore­line and bot­tom of water­ways, mak­ing the barbs of the fruits extremely painful if stepped on.

What can be done?

A vari­ety of meth­ods in con­trol­ling Water Chest­nut include man­ual, mechan­i­cal, and chem­i­cal meth­ods. Early detec­tion is the best way to con­trol and even erad­i­cate this inva­sive aquatic plant, keep­ing costs and eco­log­i­cal impacts low. Hand-pulling is often done to smaller infected areas, though, when a site is too large, har­vest­ing machines can also be used. Chem­i­cal treat­ments should be done by NYS DEC pro­fes­sion­als only.

As a local com­mu­nity mem­ber, make sure to Clean, Drain, and Dry your water­craft and equip­ment before and after each use. Be sure to dump your bait bucket water where it came from or on land.

If you think you have found Water Chest­nut, take a look at the Water Chest­nut Fact Sheet. If con­firmed, the NYS DEC asks you take many pho­tos and sub­mit a report to iMap­In­va­sives. Please share this infor­ma­tion with others!

For more infor­ma­tion regard­ing local infes­ta­tions of Water Chest­nut, check out the Eso­pus Creek Con­ser­vancy here. Thank you again for tak­ing time to explore inva­sive species with us dur­ing National Inva­sive Species Aware­ness Week!

National Invasive Species Awareness Week — Didymo (Rock Snot)

Posted on: March 1st, 2018 by Samantha Kahl

Day 4 of National Inva­sive Species Aware­ness Week is ded­i­cated to Rock Snot!

What is it?

Didy­mos­pher­nia gem­i­nata a.k.a. Didymo a.k.a. Rock Snot, is an aquatic, inva­sive, micro­scopic diatoma­ceous algae that pro­duces high vol­umes of stalk mate­r­ial, which is why you may see thick mats on stream bot­toms. It is often brown, tan, or white, with the appear­ance and tex­ture of wet wool that does not fall apart easily.

How does this impact streams?

Because Didymo grows on the bot­tom of streams and still waters, and forms thick mats of mate­r­ial, it can last for months, despite occur­ring through­out some fast mov­ing streams. When Didymo grows, or blooms, it cov­ers entire stream beds, cov­er­ing over native organ­isms, and restrict­ing the avail­abil­ity of food for native fish species. It spreads quickly and eas­ily due to water recre­ation activ­i­ties. Fish­ing, kayaking/canoeing, tub­ing, and boat­ing allows the micro­scopic algea to attach onto your boots, waders, and boats, and if not cleaned off prop­erly, it will spread to the next body of water you go to. Cur­rently, there are no con­trol meth­ods avail­able to stop the spread and erad­i­cate Didymo.

Make it stop!

NYS DEC urges the pub­lic to use the “Inspect, Clean and Dry” method to decrease the spread of inva­sive species. If for any rea­son you can’t get your equip­ment clean and dry, restrict your equip­ment to a sin­gle water body.

**Atten­tion Felt-Sole Waders! We encour­age you to con­sider other alter­na­tives, such as rub­ber stud­ded boots. Because felt-soles absorb Didymo cells and remain absorbent for long peri­ods of time, the spread of Didymo can increase rapidly if spe­cial treat­ments are not conducted.

National Invasive Species Awareness Week — Emerald Ash Borer

Posted on: February 28th, 2018 by Samantha Kahl

Happy Wednes­day! On this third day of National Inva­sive Species Aware­ness Week, we’re tak­ing a closer look at the Emer­ald Ash Borer (EAB).

Accord­ing to the NYS DEC, The EAB is a bee­tle from Asia that was first found in Michi­gan in 2002. Sadly, the EAB infests and even­tu­ally kills North Amer­i­can Ash tree species, mak­ing every native Ash tree sus­cep­ti­ble to infestation.

Let’s get a closer look!

The EAB is very small, mea­sur­ing, at most, 0.5 inches long and 0.125 inches wide. The adults have a shim­mer­ing emer­ald green body with a cop­per or pur­ple abdomen on it’s under­side. You’ll often see these pests from May through Sep­tem­ber, but their prime activ­ity months are June and July. If you pass by an Ash tree, you will most likely see D-shaped exit holes in the branches and trunk of trees. Other signs of infec­tion include the yel­low­ing and brown­ing of tree leaves and less tree canopy present. Within 2 to 4 years, the Ash trees will suc­cumb to the EAB infestation.

The EAB is found through­out the East­ern to Cen­tral United States and East­ern Canada. In New York, the first infes­ta­tion of EAB was sighted in Cat­ta­rau­gus County in 2009. It then spread to the Hud­son River Val­ley, and con­tin­ued on to more than 30 coun­ties. Infes­ta­tions were most recently found in Franklin and St. Lawrence Coun­ties in 2017.

National Invasive Species Awareness Week — Hemlock Woolly Adelgid

Posted on: February 27th, 2018 by Samantha Kahl

National Inva­sive Species Aware­ness Wood, Day 2! 

Today we are look­ing at the Inva­sive Hem­lock Woolly Adel­gid (HWA), and small aphid-like insect that attacks North Amer­i­can Hem­lock Trees. Often, the HWA look like white woolly masses (or, ovisacs) found on the under­side of branches at the base of Hem­lock nee­dles. Ovisacs con­tain up to 200 eggs and will remain on the tree through­out the year. Native to Asia, the HWA was first found in the U.S. in 1951 and has spread north ever since. These inva­sive insects cur­rently infect 43 coun­ties within New York State.

White Woolly egg ovisacs.

White Woolly egg ovisacs.

So what do Hem­lock Woolly Adel­gids do to Hem­lock trees that make them so invasive?

HWA’s hatch from the ovisacs and insert very long mouth parts into the tree, at the base of the nee­dles. The insects will remain in the same spot for the rest of their lives, con­tin­u­ally feed­ing on the starches stored within the tree. This process neg­a­tively affects the trees by tak­ing in the nutri­ents meant for the tree limbs and nee­dles. With this process affect­ing the tree, mor­tal­ity of the tree occurs within 4 to 10 years of a HWA infestation.

Hem­lock Woolly Adel­gid attached to the base of a nee­dle on a Hem­lock tree.

How do we con­trol these pests?

There are a vari­ety of meth­ods the State and other orga­ni­za­tions have col­lab­o­rated together to do in order to save our native Hem­lock trees. Through the suc­cess­ful intro­duc­tion of non-native, but non-invasive species for pre­da­tion, the HWA has been con­trolled. Insec­ti­cides have also been used to treat a tree that has already been infested or as a pre­ven­ta­tive method in a high-risk area. Though insec­ti­cides have been use­ful in treat­ing indi­vid­ual trees, large forested areas are not ideal.

What hap­pens if you think you’ve found Hem­lock Woolly Adelgids ?

The New York State Depart­ment of Envi­ron­men­tal Con­ser­va­tion (NYS DEC), sug­gests tak­ing pic­ture of the infes­ta­tion includ­ing a coin or ruler for scale, make a note of the loca­tion, fill out the HWA sur­vey form, and send over the report, plus the pic­tures you take, to DEC For­est Health You can also report the infes­ta­tion you find on the iMap­In­va­sives map and con­tact the New York Inva­sive Species Infor­ma­tion (NYIS).

Decrease the spread of HWA and other inva­sives by clean­ing any gear or equip­ment that has been in or near an infested area!
